I found the issue and here's a hint: Just because you checked something a couple days ago, don't assume it's still fine. a few days ago I checked all the clamps for the pressure side hoses and they were mostly tight. I snugged them a little more and good. Then, I get this boost gauge and it tells me 14 pounds. I worry but, don't recheck the hoses because I just tightened them a few days before. Today I check and the goddamn IC out hose is totally slacked off again and boost is blowing out there. Tighten it up and the cheapass gauge now reads 16 pounds like it should. I think T-bolts are in my future.
Worm clamps :flip:
